Su Cheng immediately understood Lu Xingtang's intentions, they could exchange disinfectant or pesticides for supplies.

Su Cheng asked clearly, and after making sure that there was no problem, he showed the list to Lu Xingtang, and the three of them immediately started to act, Lu Xingtang took out a gas mask generously, and Su Cheng's eyes were hot for a while, Lu Xingtang silently returned home, took a gas mask and gave it to Su Cheng: "Ask for money!" ”

Su Cheng happily took it: "Please eat dumplings!" ”

"It's a deal!"

Ji Yanmo looked down at the gas mask in his hand, he actually didn't need to take it out.

The main ingredient of the disinfectant is sodium hypochlorite, and the insecticide is mainly permethrin, permethrin, deltamethrin and other components.

Su Hao is a professor of chemistry, and the production of disinfectants and insecticides is pediatric for him.

According to Su Hao's reminder, they drove the assault boat to their destination, but unfortunately the building had been soaked by flooding, and they did not dare to guarantee that they could find chemical components such as sodium hypochlorite that had not been soaked through.

Coming down from the assault boat, Lu Xingtang saw that the ground and water were densely packed with insects, and the whole person was not good, and he felt that the goosebumps had fallen off.

Lu Xingtang took out a pair of gloves from her backpack and put them on, she had already worn a pair, she couldn't stand the insects on the ground, on the wall, and in the water, so she brought another pair, if it weren't for wearing protective clothing that was too eye-catching, she would definitely wear it.

Entering the building, the three of them began to rummage, allowing them to find a lot of chemical tools, but they were very dirty and dirty with blisters, and all the instruments were covered with bacteria and insect eggs.

They rummaged for about three hours, so that they finally found out the chemical ingredients for making disinfectant and insecticide, and then took the items that could be taken home, before taking them upstairs, Su Cheng quickly went upstairs, took out the disinfectant water and disinfectant tissues at home, disinfected the packaging of utensils and chemical materials, wiped them clean, and then took them back to the 19th floor.

They started to make disinfectant water only after they had successfully disinfected all the utensils, and Su Hao pointed out on the side.

In ten minutes, the three of them successfully won the method of making disinfectant water, and after making a bucket of disinfectant water, they used the stairs and corridors on the 19th floor to conduct experiments, and Lu Xingtang was surprised to find that the disinfectant he made was even better than the one he bought.

Then make insecticides, the effect of insecticides is not bad, they spray the insects attached to the exterior wall, and they die when they spray, it is really an insecticidal artifact.

That night, Min Weihuan came back with the residents of the unit building who went to the hospital to see a doctor, and saw that they were all depressed, and Lu Xingtang probably knew the situation.

After the parasitic infection in the previous life, the hospital was suddenly overcrowded, there were few doctors and medicines, and it didn't take long for the medicine to run out, no matter how everyone waited at the entrance of the hospital, they couldn't wait for the medicine to appear.

However, people who went to the trading market had a little harvest and brought back some medicines, but there was no way, so everyone divided a medicine into two or three parts, and took medicine according to the severity of the disease, taking one-third of a medicine for the light, two-thirds for the general, and one for the heavy.

The medicine taken with water is a large glass of water, and several people drink it separately.

Anyway, there is medicine to drink.

Min Weihuan felt very uncomfortable when she saw the residents distributing medicine for their lives, and found Lu Xingtang again: "Lu Xingtang, I know that the three of you are good at finding supplies, you must have a way to find medicine, you see, help us, we are willing to spend expensive food to exchange medicine with you!" ”

When the residents from the trading market came back, they brought back the medicine, and also brought back a message, saying that the materials they received every week were still the same, and they could still go to receive the supplies.

Lu Xingtang looked at Min Weihuan full of grief and despair, thinking that there was a lot of medicine in the space, she agreed to help the people in the unit building find medicine, and the price in the trading market would prevail, and she would not knock on the bamboo bar of the unit building.

Min Weihuan was overjoyed, so he sent Lu Xingtang to kneel, so he immediately told the people in the unit building the news, and the people in the unit building came to thank Lu Xingtang, saying that they would definitely gather the materials to get the medicine from her.

Lu Xingtang sent them back, leaving Min Weihuan: "We have developed disinfectant water and pesticides, do you want them?" If you want, for your sake, give a friendly price, a pound of grain, mineral water, disinfectant water or a mineral water bottle of insecticide. ”

Min Weihuan has already asked people to inquire in the trading market, 500ml of disinfectant costs eight catties of grain, pesticides are more expensive, and the effect is not good, even 10 catties of grain and 500ml.

Lu Xingtang gave them the price of jumping off the building, how could Min Weihuan miss it, and immediately exchanged ten catties of disinfectant and pesticides with Lu Xingtang.

With disinfectant and pesticides, their unit building is much safer.

"Min Weihuan, how about we make a deal?" Lu Xingtang didn't want to sell disinfectant in the scorching sun, Min Weihuan and they lacked materials, medicines, and pesticides, "You find a few reliable people to sell insecticides and disinfectants in the unit building of the community, two catties of grain 500ml disinfectant, two catties of grain 200ml insecticide."

As long as you sell, no matter how much you sell, I will give you supplies or clean water as a reward, and then it depends on whether you need food or water, and what you want! ”

The last thing she lacks is water, and there is a constant stream of water in the space, and there will be no shortage at all!

When the water hoarded outside runs out, they will find a way to find water 'outside'!

Min Weihuan was as happy as a child: "Great, great!" Our unit building is saved! ”

Su Cheng and Ji Yanmo have no objection to Lu Xingtang's decision, they understand that the business of disinfectant and insecticides will not last long, because under the extreme high temperature, the water level drops seriously, how long can all kinds of bugs and viruses survive in extreme heat? Maybe by the time the water level is back on the first floor, all the bugs and viruses will be dead.

Depending on how much the water level is currently dropping, it will be gone in about three or four days.

There is less water, but there are a lot of supplies that can be exchanged for disinfectant and pesticides, and no matter how you count them, they also make money.

After Min Weihuan told the residents of the unit building the news, they all became a sensation, and they immediately went upstairs to find Lu Xingtang and them, saying that they could go out to sell disinfectant and pesticides now, and they would definitely do their duty and would never take away a single cent of materials on the 19th floor.

Lu Xingtang handed over this task to Ji Yanmo and Su Cheng, because she was going out to look for medicine.

Ji Yanmo didn't worry about Lu Xingtang, even if he knew that Lu Xingtang was just looking for a name to go outside, and he would definitely be able to find medicine when he came back, but it was particularly dangerous to go out at night, and he said that he wanted to go out with Lu Xingtang, Lu Xingtang wanted to refuse, but Su Cheng helped Ji Yanmo speak, so that Lu Xingtang's words of refusal were held back, Lu Xingtang understood that Su Cheng and Ji Yanmo were just worried about their own safety, hesitated, and agreed.

The risk of bringing Ji Yanmo is low, and the risk of Su Cheng is too high.
